Jenson used to be the Commander of the North American Resistance until, one day, he was found dead in a mountainside cabin. He'd used that cabin as a personal place to retreat to whenever he needed to relax, only a few high-ranking people at the base knew that he used it. He appeared to have been murdered, but the Resistance couldn't find any evidence as to who might've done it, human or Arume. He was replaced by Commander Aki, as appointed by the Leader of the Resistance.
